A Porous Media Regeneration Microscale Burner

Abstract

The invention relates to a microscale flat plate type regenerative burner filled with porous media. The burner comprises a channel formed by an air inlet, an air outlet and a burner outer wall, wherein one end of the channel is closed and a T-shaped partition board is arranged at the other end of the channel. The T-shaped partition board is composed of a transverse partition board and a longitudinal end board, wherein the transverse partition board extends into the channel, the length of the transverse partition board is shorter than the length of the channel, the porous media are arranged on both an upper area and a lower area of the transverse partition board, the longitudinal end board is arranged on an end opening position of the other end of the channel, and the air inlet and the air outlet are both formed in the longitudinal end board and are symmetrically distributed at two sides of the position of the transverse partition board. According to the microscale flat plate type regenerative burner filled with porous media, a rectangular channel in the burner is divided into two areas by a middle heat conducting partition board, thus regenerative burning is realized. Due to the fact that the design which combines the porous media with the regenerative burning is adopted, microscale burning process in the channel is enabled to be sufficient and stable, and radiation wall temperature distribution is high and uniform, and accordingly positive effects for enhancing output property of a miniature thermal optoelectronic system are generated.

Description

technical field [0001] The invention belongs to the field of micro power electromechanical systems (PowerMEMS, referred to as micro power systems), and belongs to a new regenerative combustion technology, in particular to a micro-scale flat regenerative burner filled with porous media. Background technique [0002] In recent years, with the continuous deepening of research on micro-electro-mechanical systems (MicroElectro-MechanicalSystem, referred to as MEMS), the issue of micro power supplies has gradually attracted widespread attention. When the electromechanical system is miniaturized, the size of its power supply or power device will determine the size of the entire system. Without a miniaturized or miniaturized power device to provide energy and power for it, it will be difficult for the MEMS system to take advantage of its miniaturization, or even There is a risk of losing the inherent significance of its miniaturization. In such a context, the micro power system (Po...

Problems solved by technology

[0005] However, the efficiency and power density of the miniature thermoelectric system are still satisfactory, and there is still a long way to go before the actual application of the device. There are many reasons for this, and one of the more prominent points is the most important part of the system—— Micro-scale burners, the effect of the internal combustion organization has not yet reached the best state, resulting in the overall temperature of the radiation surface is not ideal
